8. TrIFOLIUM MICROCEPHALUM, Pursh, F'., ii. 478. 
9. Lupinus MicraNruus, Dougl.; Bot. Reg. t. 1251. 
10. Lupinus aLBirrons, Benth.; Bot. Reg. t. 1642. 
11. Osmaronta cerasirormis, (Torr. & Gray), Greene, 
Pitt. ii. 191. On the north side. 
12. HereroMeLes arputirouia (Ait. f.), Roemer, Syn. 
Monogr. iti. 105. 
13. Hozopiscus piscotor (Pursh), Maxim. Adn. Spir. 150. 
Only very near the summit. 
14. ApENosroma FasctcuLatum, Hook. & Arn. Bot. Beech. 
139. Forming extensive and dense thickets on all the more 
elevated slopes, at least to the southward. 
15. Ruus piverstiopa, Torr. & Gray, Fl. i. 218. Reduced 
in size, but more frequent than on Mt. Hamilton. 
16. RHamNus TomENTELLA, Benth. Pl. Hartw. 303. In 
dry ground only, less pubescent than the type. 
17. Raamnvs rtcrronia, Kell. Proc. Calif. Acad. ii. 37. 
Not rare near the summit, forming dense well rounded clumps 
of bushes four to six feet high. Although this was admitted, 
in the Flora Franciscana, as but a variety of R.crocea, we have 
now seen so much of the constancy of character in the sea- 
board undershrub that we no longer doubt the distinctness of 
the larger and much more common species of the higher hills 
and farther foothills which Dr. Kellogg was first to segre- 
gate and name. At the eastern base of Mt. Diablo, along 
Marsh’s Creek and elsewhere near the plains the species 
attains the height of ten feet or more, and is more tree-like 
in aspect. 
“18. CEANOTHUS cungatus (Hook.), Nutt.; Torr. & Gray,

other like elevations of the middle Californian mountains.
